Computer: Dell Dimension 5100. 6 years old.
Current hard drive: SATA 250GB (think it's SATA 1). Dell web site says its ATA-133

Looking to: Replace the hard drive due to faults

Question: Can I fit a SATA 3 hard drive in this computer? Would this just work at SATA 1 speeds because of the old mainboard? Most of the hard drives listed for sale are now SATA 3.

Thanks for any replies.

The Sata 3 will work as it is backwards compatible. Some models you may have to set a jumper but that will be detailed in the manual or manufactures website.


Edit: I read the op too fast missed the ata-133. If you have a sata 1 mobo or controller a sata 3 would work. However you do not have sata you will need a different drive.

Welcome to Techguy, ffg! Your computer doesn't support SATA drives. so, you either need to buy an IDE drive as a replacement, or spend a few bucks for a SATA controller. Since I expect the machine is running XP, you are really better off using an IDE/PATA drive rather than adding an aftermarket controller. Sticking with an IDE drive means that you avoid hassles like needing a floppy disk with the controller driver on it when you re-load Windows. In practical terms, you wouldn't see much benefit from a SATA drive and controller; it would just be more money and more annoyance. All of the current hard drive interfaces exceed the performance of a standard hard drive. You have to get into SSDs before the bus limits performance.

Just googled system and yes you do have two sata Ports. You had mentioned ata-133 which is ide related not sata. So yes like I said originally you will be fine with a sata 3 drive just make sure you check documentation for any drive jumper settings

I got that ATA-133 bit from the BIOS info earlier.

Thanks for confirming that SATA 3 will work.

The other thing I can't find in the system manual or Dell website is the maximum size that the 5100 will take. Some Google searching shows that a 500GB will work (will be enough for me), but do you reckon a 750 or 1TB would work?

Thanks.

I can't find any instant information on size limits for the controller. I did find others using 1tb fine so you should be okay up to 1tb.

Sent on the go. Please excuse spelling and punctuation errors.

The reason BIOS is showing ATA-133 is because BIOS is set to configure SATA drives as IDE. I would leave the setting as is.

Some of the early SATA boards will work just fine with a SATA 3 drive and others need the jumper set to 1.5GB transfer speed. On early boards with the 1.5GB SATA controllers I automatically just go ahead and jumper the drive to the 1.5GB transfer rate before I install it so if the drive has a problem with the slower controller I don't have to bother with pulling the drive again to set the jumper.

I have the latter version of your PC, dell dimension 5150. I can confirm up to 1tb HDDs will work. Also SSD's will work perfectly and very quickly.
